Book Synopsis Diesel Particulate Filter Regeneration with an External Burner by : Kenneth Michael Follen

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Particulate matter has been identified by health agencies as a health risk and suspected of causing acute and chronic damage to the pulmonary and cardiovascular systems. Since diesel engines are well known for their soot production, legislation has been adopted to regulate the release of particulate matter into the atmosphere. As these emissions standards become increasingly stringent, new methods of emission control become necessary. Of the options currently available, particulate filters appear to be the most promising solution to meet and exceed these emission standards. Particulate traps have been shown to successfully filter out up to 90 % of particulate matter. However, as particulate traps filter particulate matter they become filled, resulting in an increase in the exhaust back pressure. To alleviate this increase in pressure, the filter must be regenerated, i.e. the particulate matter must be ignited and burned away leaving a clean trap. Of the current regeneration methods, active regeneration via an external burner is one of the more robust methods. The scope of this work is to design a fuel-fired heater for the purpose of supplying sufficient quantities of heat to elevate the exhaust temperature to the point at which diesel particulate filter (DPF) regeneration will occur. As a precursor to the design, an in-depth literature review on the current state of the art, as well as calculations of the design.

Book Synopsis Modeling and Analysis of Particulate Matter Deposition and Regeneration in a Diesel Particulate Filter by : Mengting Yu
Download or read book Modeling and Analysis of Particulate Matter Deposition and Regeneration in a Diesel Particulate Filter written by Mengting Yu and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engines are widely used because of their high efficiency and low “greenhouse gas” emission. The particulate matter (PM) emitted by a diesel engine is collected and then burned in a diesel particulate filter (DPF). Analysis and modeling works have been done in this research to provide insight on optimization of the DPF design and operating conditions to achieve low pressure drop across the filter to decrease fuel consumption and low peak temperature during regeneration to avoid filter melting, cracking, and/or catalyst deactivation. Limiting models of the 1-D two-channel DPF model are analyzed. Analytical predictions and physical insight on the filtration velocity, pressure drop, heat transfer, light-off and regeneration in a DPF are obtained. The hydraulic analysis enables an efficient optimization of the DPF that lead to a more uniform PM deposition profile and a decrease of the pressure drop. The heat transfer, light-off and regeneration analysis enable estimations of the DPF heat-up time, the speed and width of the temperature front, the light-off temperature and time, and the peak regeneration temperature. New DPF regeneration procedures are proposed to limit the maximum local temperature rise. In various cases a DPF is connected by a wide-angled cone (diffuser) to the engine exhaust pipe. A 2-D axisymmetric PM deposition and regeneration model is developed to investigate the impact of the inlet cone on the deposition rate and the regeneration temperature as well as on the transient inlet velocity distribution among the various DPF channels. The highest regeneration temperature and thermal stress when using an inlet cone may be quite higher than when it is absent. A major technological challenge in the regeneration of the ceramic cordierite filter is that a sudden decrease of the engine load, referred to as Drop to Idle (DTI), may create a transient temperature peak much higher than under either the initial or final stationary feed conditions. This excessive transient temperature rise may cause local melting or cracking of the ceramic filter. Suggestions on how to limit the peak temperature rise following a DTI are provided through numerous simulations of the 1-D and 2-D DPF regeneration models.

Book Synopsis Simulation of Diesel Particulate Filter Regeneration Using Lattice Boltzmann Method by :
Download or read book Simulation of Diesel Particulate Filter Regeneration Using Lattice Boltzmann Method written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Lattice Boltzmann Method is a novel approach, which has shown promise in solving a wide variety of fluid flow problems including single and multi-phase flows in complex geometries. Volume elements of the fluid domain are considered to be composed of particles and these particles fall under a velocity distribution function at each grid point. Particles collide with each other under the influence of external forces and the rules of collision are defined so as to be compatible with the Navier-Stokes Equation. In the current work, LBM has been applied to Diesel Particulate filters which is a device used for reducing Particulate Matter emissions from diesel engines. Diesel Particulate Filtering (DPF) technologies as they are collectively known, have a two-step mechanism to them. First is the trapping of the particulate matter and second is the regeneration process, which is essentially the cleaning process applied to get rid of the trapped soot with or without the help of catalytic compounds. The deposited soot is oxidized during this regeneration process. This oxidation of soot has been modeled in the current work using LBM. An artificially created porous microstructure as used by authors in some earlier works has been used to simulate the flow of fluid, which is considered to have a specified mass fraction of soot for different runs of the simulation. The velocity and concentration fields have been modeled with a D2Q9 lattice arrangement and the temperature field with a D2Q4 arrangement. The numerical code is developed using C. Flow over a heated cylinder has been modeled as a benchmark case. The pressure, velocity, temperature and concentration contours for the disordered media are compared with published work.
